OBJECTIVE: Recently, regenerative therapies have been used in clinical trials (heart, cartilage, skeletal). We don't make use of these treatments to spinal cord injury (SCI) patients yet, but regenerative therapies are rising interest in recent study about SCI. Neural precursor/stem cell (NPSC) proliferation is a significant event in functional recovery of the central nervous system (CNS). However, brain NPSCs and spinal cord NPSCs (SC-NPSCs) have many differences including gene expression and proliferation. The purpose of this study was to investigate the influence of neural growth factor (NGF) on the proliferation of SC-NPSCs. METHODS: NPSCs (2×10⁴) were suspended in 100 µL of neurobasal medium containing NGF-7S (Sigma-Aldrich) and cultured in a 96-well plate for 12 days. NPSC proliferation was analyzed five times for either concentration of NGF (0.02 and 2 ng/mL). Sixteen rats after SCI were randomly allocated into two groups. In group 1 (SCI-vehicle group, n=8), animals received 1.0 mL of the saline vehicle solution. In group 2 (SCI-NGF group, n=8), the animals received single doses of NGF (Sigma-Aldrich). A dose of 0.02 ng/mL of NGF or normal saline as a vehicle control was intra-thecally injected daily at 24 hour intervals for 7 days. For Immunohistochemistry analysis, rats were sacrificed after one week and the spinal cords were obtained. RESULTS: The elevation of cell proliferation with 0.02 ng/mL NGF was significant (p<0.05) but was not significant for 2 ng/mL NGF. The optical density was increased in the NGF 0.02 ng/mL group compared to the control group and NGF 2 ng/mL groups. The density of nestin in the SCI-NGF group was significantly increased over the SCI-vehicle group (p<0.05). High power microscopy revealed that the density of nestin in the SCI-NGF group was significantly increased over the SCI-vehicle group. CONCLUSION: SC-NPSC proliferation is an important pathway in the functional recovery of SCI. NGF enhances SC-NPSC proliferation in vitro and in vivo. NGF may be a useful option for treatment of SCI patients pending further studies to verify the clinical applicability.

PURPOSE: The objective of this study was to examine the correlation between HbA1C, self-care behavior, and quality of life among depressed and non-depressed patients with type II diabetes. METHODS: Data were collected between May 26 and July 5, 2011 using a questionnaire. The questionnaire included depression (CES-D), self-care behavior and quality of life. Hemoglobin A1C was abstracted from medical records. Data were analyzed by descriptive statistics, t-test, chi2-test, ANCOVA and Pearson's correlation coefficient. RESULTS: In this study sample (n=301), 20.9% of diabetic patients (n=69) were depressed. After adjustment for relevant covariates, depressed patients showed to have lower self-care behavior (2.8 vs 3.4, p<.001) and quality of life (2.8 vs 3.5, p<.001) scores, but the difference in HbA1C was no longer significant. CONCLUSION: This study suggests that the assessment and intervention for depressed diabetic patients can result in effective self-care behavior, which accordingly leads to improvement of the quality of life.

PURPOSE: Coronary artery abnormalities (CAA) are the most important complications of Kawasaki disease (KD). Iron deficiency anemia (IDA) is a prevalent micronutrient deficiency and its association with KD remains unknown. We hypothesized that presence of IDA could be a predictor of CAA. METHODS: This retrospective study included 173 KD patients, divided into 2 groups according to absence (group 1) and presence (group 2) of CAA. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a logistic regression model to estimate the association between CAA and other indicators. Due to collinearity between indicators of IDA, each indicator was paired with anemia in 3 models. RESULTS: Serum iron, iron saturation, and ferritin concentration, the 3 indicators of IDA, were significantly higher in group 1 than in group 2. Three sets of models including anemia with iron indicators produced the OR of CAA of 3.513, 3.171, and 2.256, respectively. The 3 indicators of IDA were negatively associated with CAA, by OR of 0.965, 0.914, and 0.944, respectively. The areas under the curve (AUCs) of ferritin concentration, iron saturation, serum iron, anemia, and Kobayashi score were 0.907 (95% CI, 0.851–0.963), 0.729 (95% CI, 0.648–0.810), 0.711 (95% CI, 0.629–0.793), 0.638 (95% CI, 0.545–0.731), and 0.563 (95% CI, 0.489–0.636), respectively. CONCLUSION: Indicators of IDA, especially ferritin, were highly associated with CAA; therefore, they were stronger predictors of CAA than Kobayashi scores. IDA indicators can be used to predict CAA development and to suggest requirements for early interventions.

BACKGROUND/OBJECTIVES: The purpose of this study was to evaluate the feasibility of application of the draft nutritional standards for school lunches in the Republic of Korea (South Korea) from the supplier perspective. SUBJECTS/METHODS: In November 2018, a pilot operation was conducted at 104 participating schools for 2 weeks each by applying the draft standards A and B. To evaluate the ease and appropriateness of application of the standards, we analyzed the nutritional values and food cost of the school lunches for 2 weeks before and for 4 weeks under the pilot operation. We conducted an online survey of school dietitians or nutrition teachers of the participating schools to evaluate the feasibility of application of the standards in school lunch sites. RESULTS: The proportions of schools of which lunches met the reference values of the school’s own nutritional standards were 19.2% for the standards A and 21.2% for the standards B. The food cost of school lunches applying the standards A (KRW 2,880) was significantly lower than that of school lunches applying the standards B (KRW 3,030) or the existing standards (KRW 2,980). As a result of the survey, the mean score for the ease of application was significantly higher for the standards B (2.75) than for the standards A (2.24). The proportions of school dietitians or nutrition teachers reporting no problem in meeting an existing food cost standard were 72.5% for the standards A and 61.8% for the standards B, respectively. The overall appropriateness of application was higher for the standards B, because almost two-thirds (58.8%) of the respondents answered that the standards B were more appropriate than the standards A. CONCLUSION The standards B were more feasible to apply as nutritional standards for school lunches than the standards A from the supplier perspective.

BACKGROUND: Paraneoplastic neurological disorders associated with anti-Ri-antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Most cases with anti-Ri-antibodyassociated paraneoplastic syndrome due to breast cancer occur in women - its occurrence in men is extremely rare. CASE REPORT: We present herein the case of a male patient with breast cancer who had atypical anti-Ri-antibody-associated paraneoplastic syndrome presenting as complete horizontal ophthalmoplegia, left trigeminal sensory symptoms, and truncal ataxia. Following the diagnosis of paraneoplastic syndrome, chemotherapy and immunomodulating treatment including intravenous immunoglobulin and oral prednisolone were administered. Although the patient was negative for serum anti-Ri-antibodies 14 weeks later, his symptoms persisted. CONCLUSIONS: To our knowledge, this is the first case report of ophthalmoplegia without opsoclonus-myoclonus in a male anti-Ri-antibody-positive patient with breast cancer.

PURPOSE: The purpose of this study was to identify the influences of recognition on low fertility and views of marriage on childbirth will in university students. METHODS: Participants were 190 university students in Chungchungnamdo province, Korea. The data were collected from May to October 2018 and examined using descriptive statistics, t-test, analysis of variance, Pearson correlation and multiple regression with IBM SPSS Statistics ver. 24.0. RESULTS: Childbirth will was significantly correlated with recognition on low fertility (r=0.20, p=0.002) and views on marriage (r=0.53, p<0.001). Factors associated with childbirth will were views on marriage (β=0.24, p<0.001). CONCLUSION Theses results suggests that views on marriage have important influences on childbirth will in university students. To improve childbirth will, the positive views on marriage need to be formulated in university students.

Purpose: The importance of laboratory screening tests for female commercial sex workers (FCSWs) has been well documented to reduce the prevalence of chlamydial complications. A rapid test has been one of the standard chlamydial tests performed in Korean health centers. Although the process of the rapid test is simple, the sensitivity is inconsistent. Therefore, we evaluated the efficacy of QuickVue chlamydial detection kits, which is one of the rapid tests, by comparing this assay to an in-house polymerase chain reaction (PCR) method. Materials and Methods: A total of 410 endo-cervical samples were consecutively collected in one health center. A rapid test was performed by using a QuickVue kit. Genomic DNA was extracted from cotton swabs. The cryptic plasmid of C. trachomatis from the genomic DNA was amplified by the PCR method. Results: The overall sensitivity, specificity, positive predictive value and negative predictive value of the rapid test were 21%, 99%, 89% and 83%, respectively, based on the PCR results. Study of the serial dilutions of reference inclusion forming units (IFU) showed that the rapid test only detected chlamydial infections that had high counts of IFUs. Conclusions: The rapid test is not good enough to detect chlamydial infection in FCSWs. Instead, a gene amplification test should be used for detecting chlamydial infections in FCSWs.

The purpose of this study was to examine restaurant customers' use of menu labeling and their perception of menu labeling attributes. Further, the study investigated relations of menu labeling use behavior, and perception of menu labeling attributes with behavioral intentions toward menu labeling. Using a self-administered survey conducted for 2 weeks from the 2nd week of October, 2015, data were collected from restaurant customers who were exposed to menu labeling over 3 months at the time of the survey. A total of 426 respondents completed the survey. Respondents were asked about use of menu labeling, usefulness, ease of understanding, accuracy, and demographic information. There was a difference in menu labeling use behavior according to age, whereas respondents aged 50 years or over showed significantly higher use of menu labeling than those in 20s (P<0.001). Perceptions of menu labeling attributes positively affected behavioral intentions towards menu labeling. While all three menu labeling attributes, ‘usefulness’, ‘ease of understanding’, and ‘accuracy’, were positive factors for behavioral intentions towards menu labeling, usefulness was the biggest attribute explaining behavioral intentions (P<0.001). The study findings offer implications that can be applied to academics, the foodservice industry, and government in an attempt to nurture a healthy eating environment through provision of nutritional information at restaurants.

This retrospective study reviewed clinical and electromyographic (EMG) findings in 106 patients with cervical pain syndrome. The purpose of this study was to test the validity of clinical tests (neck compression test, manual muscle test, sensory test, deep tendon reflex) in the diagnosis of cervical radiculopathy. Electromyographic studies were interpretated as positive finding with the presence of abnormal spontaneous activities of limb and paravertebral muscles and the clinical tests were interpretated by the presence or absence of abnormalities. The results showed that the neck compression and manual muscle tests correlated well with the EMG findings but the sensory test and deep tendon reflex were not. It is suggested that the neck compression and manual muscle tests may be helpful in the diagnosis of radiculopathy.

Bioelectrical impedance analysis (BIA) has been used to investigate the body compositions and predict functional outcomes in patients with stroke, while the role of BIA to predict motor function or recovery in stroke has not been clarified. This study aimed to investigate relationship between body composition measured by BIA and upper limb motor function and recovery. Body compositions (soft tissue lean mass, phase angle, body fat mass and body water) of fifty patients who are admitted to the stroke rehabilitation unit were segmentally analyzed via BIA. The motor recovery of upper extremity (UE) was evaluated via Fugl-Meyer Assessment (UE-FMA) at the time of transfer and discharge. Correlations between body composition and UE-FMA at discharge were analyzed using Spearman correlation coefficient.Multiple regression analysis was used to determine the regression between body composition and motor function and recovery. The Δ Phase angle, the difference of both sides was significantly linearly inversely correlated with UE-FMA at discharge. However, in multiple regression analysis, body compositions including phase angle did not significantly predict motor function at discharge or motor recovery. The Δ Phase angle is related to the severity of upper limb motor function at discharge in subacute stroke patients, and further studies are needed to determine its value as a predictor for motor recovery.
